If you are sport fishing in Costa Rica, expect to see some extraordinary fish that you may have never seen up close. Sailfish and Marlins are among the most sought-after game fish in the world, and we have both here in Costa Rica! The Marlin here can get up to 600 pounds, and we have both the black and the blue varieties. Sailfish fishing is great because it goes strong year ‘round! There may be certain times that are better than others, but the numbers are high all year.
